Abstract:Research purposes: Based on the grading method for the surrounding rock of railway tunnel stipulated in the<>.the principle of probability is used in grading the surrounding rock of railway tunnel,the study is done on the correlativity of grading indexes and the probability model is established for grading surrounding rock of railway tunnel with correlativity—based quantitative analysis for providing the reference to survey,design and construction of railway tunnel.
Research conclusions:The correlativity—based probability grading method was used for grading calculation of the surrounding rock of Nanliangshan Tunnel and Taihangshan Tunnel of Shijiazhuang—-Taiyuan Passenger Dedicated Line and the calculation results fit to the real situation of the surrounding rock of the tunnels after comparing it with the real surrounding rock.It shows the real situation of the surrounding rock can be reflected with this method and this method is an effective way of grading the surrounding rock of railway tunnel.
